I have a Tbird 800 and I used the pencil trick with #2 graphite pencial lead to close the L1 bridges on my chip. I am now overclocked succesfully at 850 but moving to 900 fails to post on boot up. I tried moving the voltage up to 1.8 and even 1.85. I then tried 950 just to be sure but same results each time. While I am aware that all chips are not created equal, is it possible I do not have enough graphite to close the bridges? I find it hard to believe that my processor can only overclock 50mhz. Any suggestions, help?

This is something many of us have experienced. I don't know the answer but I do know that it would not got to 850 if the bridges were connected incorrectly.
I have a Duron 600 that goes to at least 1Ghz, but my friend has a Duron 700 that can't get past 850.
We put his Duron 700 in my computer and it went to 1GHz just fine. I am suspecting the powersupply. He has a 300W and I have a 430W. That is the only difference in our computers, right down to the ram, the bios version of our A7Vs, HSF, sound card.
 
Interesting, I also have a 300Watter. I guess Ill settle for a whopping performance gain of 6.25%. ill give a very unenthusiastic woohoo to that.

cool, thanks ive seen that before but forgot all about it. so does anyone know what has a higher graphite content than #2's? #3's? I dont know how that works

thanks guys, i got it runnin at 900 now, goin for a gig by the end of the night

Well, I seem to have hit the roof at 950 (from Tbird 800). Just to be sure I want you guys to double check my symptons at 1ghz: the computer wouldnt post at 1.8v so I pumped it up to 1.85. At this VCORE, the BIOS would boot, but Windows 2000 Pro would never get past the intitial loading screen (i.e black and white). It would either crash during the load or would just restart altogether. I took this as a sign that my chip wouldn't run at 1ghz so I am now at 950 at 1.8v. Here is the WCPUID clipboard copy

Well, it seems 3dmark ran beautifully for 5 minutes then flipped out to the desktop, is this a keeper or do i need to up some voltage?

I'm no expert but I'd try running it several times to make sure it wasn't a fluke. If you can recreate the same problem often enough then I'd go ahead and bump the voltage up to 1.85 and see if that fixes it. If it does then check your temp. after 3dmark has run several minutes if your temp is ok then good. If the temp is on the high side then either get better cooling or go back down 50. If you can't get it up to the next level you could always try bumping the bus up a little and squeeze a little more out of it that way.

should i be playing around with the i/o voltage on apollo kt133 chipset? ive heard about it mostly from p3 overclockers

If you mean bumping the FSB up then i believe you can. I've never tried it though. From what I've read you can't play w/ it too much though. 110 is about the max anything will do and you probably won't get that.
p.s. i'd also get a second opinion.

oh and yea you can fsb o/c i know that, but i mean playing with e i/o voltage (i.e the 3.3v setting).
I also got 3dmark to run through its suite successfully a couple times and it only heated up to 50deg C max. not bad id say

if you have the ability on your board to adjust your i/o go ahead and try it but i don't think it will help.
try dropping back down to 8.5 multiplier and ease you fsb up to between 110 and 115. also make sure the thermistor in the socket makes firm contact with the back of the cpu and shoot for temps below 50c.

who is more foolish...
the fool, or the fool that takes his advice?
 
So can anyone explain why my friend and I have the same setup except for the powersupply and his chip doesn't go past 850 but when we put his chip in my computer it goes up to 1GHz.
The same lead pencil was used for both chips.
 
Try swaping power supply's to further isolate the problem if his goes up to 1ghz with your PS than there is the problem. If that doesnt work try with the mobo.

go into motherboard monitor and check the 3.3 volt output
could be the problem.
could also be just the differrence of the tolerances in the components of the motherboards

bubba, overclockers.com has an article about the very problem youre having, its probably the motherboard

I'm not sure but I think I found what you are talking about. They are using DDR mobos with 133 FSB. I am just talking about normal A7Vs with 100 FSB and just changing multipliers.
I need to find time to switch powersupplies. Its either the mobo or the powersupply.
I know it is not the chip.
 
im sorry, i looked for the article but i think they threw out the old ones and filled it up again with brand new ones, in other words i cant find it. ill try to remember what it said and get back to ya if i do
